Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), and the description goes beyond them by specifying the shape of what comes back panel by panel, including comparative change vs the prior period. It stops short of disclosing payload size, latency, or how project/service scoping narrows the result set.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence that front-loads the core idea ('One team dashboard read out panel by panel') and then spends its length on a compact enumeration of panel types. Nothing is redundant with the schema or annotations, and every clause carries information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description must carry the return-value burden, and it does so by naming the panel families and the comparison semantics. Given four fully documented parameters and complete annotations, the remaining gap is minor: no hint about read cost, panel count, or behavior when a panel is empty.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so each of the four parameters (including the range enum defaulting to the dashboard's own) is already documented. The description adds no parameter-level guidance such as how 'service' partial narrowing behaves or what a project-scoped read omits, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description makes clear this reads a single team dashboard and enumerates the panel content returned (current metric plus delta, rankings, monitors/checks/promises, open incidents, deploy/incident commentary). The singular 'One team dashboard' implicitly contrasts with the list-oriented relia_dashboards sibling, though it never names that tool explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is only implied: the focus on 'One team dashboard' suggests this is the per-dashboard read rather than the dashboard listing, and the panel inventory hints at what questions it answers. There is no explicit when-to-use, when-not-to-use, or named alternative among the many siblings (relia_status, relia_uptime, relia_dashboards).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
